“He’s launching a blatantly racist attack on four duly elected members of the United States House of Representatives, all of whom are women of color,” said Representative Ilhan Omar of Minnesota, a Somali refugee whom Mr. Trump falsely accused of praising Al Qaeda.

Asked whether he was concerned that his comments were racist, Mr. Trump said, “It doesn’t concern me, because many people agree with me. All I’m saying is if they want to leave, they can leave now.”

Go deeper: Mr. Trump’s telling the lawmakers to “go back” to their countries (three were born in the U.S., and the fourth is a naturalized citizen) was a painful reminder for those who have heard versions of the slur.

News analysis: Republicans’ muted response to Mr. Trump’s remarks illustrates both his grip on the party and their belief that an attack on progressivism should be central to the 2020 campaign, our chief Washington correspondent writes.

The Daily: In today’s episode, a Times reporter who covers Congress discusses the dispute.

Five Democrats stand out in fund-raising race

Pete Buttigieg and Elizabeth Warren more than tripled their fund-raising from the first quarter, according to reports filed with the Federal Election Commission on Monday.

Another angle: Of the $68 million raised in the second quarter by President Trump’s campaign committees, 35 percent came from small donors, defined as those who gave $200 or less. That’s a significant increase over the first three months of the year.

President Trump argues that migrants are gaming the system by falsely claiming asylum and then failing to appear in court. The wait for a hearing can be years because of a backlog of more than 900,000 immigration cases.

Guatemala and Mexico have refused to go along with the plan, and the rule is expected to be immediately challenged.

The woman entangled with Jeffrey Epstein

Ghislaine Maxwell, the daughter of a British media baron, arrived in New York in the early 1990s and was soon on the rise with the help of her new boyfriend, Mr. Epstein.

With Mr. Epstein facing charges of the sexual exploitation of young women and girls, there are growing questions about his relationship with Ms. Maxwell. Their romance ended, but for more than a decade she helped manage Mr. Epstein’s homes, facilitate his social relationships and recruit masseuses, according to his former employees.

Yesterday: Prosecutors argued that Mr. Epstein should be denied bail, revealing that a safe in his mansion held “piles of cash,” diamonds and an expired passport from a foreign country with Mr. Epstein’s photograph and a fake name.

Is it time to play with spaceships again?

Today is the 50th anniversary of the launch of Apollo 11, the mission that landed on the moon. The milestone comes as space travel has again entered the national conversation.

Late-night comedy: Seth Meyers noted that most of the congresswomen whom President Trump told to “go back” to their home countries are from the U.S.: “If you’re asking them to fix the totally broken, crime-infested governments of their home countries, they’re trying.”

Now, a break from the news

Smarter Living: Sibling fights offer opportunities to help your children learn to hear each other and work on their own solutions. Instead of trying to referee, narrate what you experience like a sportscaster. For instance: “I’m hearing loud voices. One of you looks angry and one of you is laughing.” Listen, stay neutral and consider what might lie beneath the surface of the fight.

Bail, he wrote, is a payment to the court — either in cash or through a pledge of personal assets — that is returned only if a defendant shows up for trial. It has roots in English common law.

By the early 1800s, private businesses (bail bond companies) were allowed to post bail in exchange for payments from defendants and were empowered to chase down any defendants who failed to appear (bounty hunting).

Commercial bail bond companies dominate the pretrial release systems of only two nations: the U.S. and the Philippines, a former U.S. territory.
